The movable supporting subassembly comprises two transmission members and two driving members. The two transmission members are laminated together and disposed on the worktable. The two driving members are respectively assembled to the two transmission members and drive the two transmission members to slide along different directions, thereby supporting the workpiece. The present disclosure further discloses a positioning assembly. | 09-11-2014 |
| 20150121980 | SHAPING METHOD FOR METALLIC MATRIX - A metallic matrix shaping method is provided. A flatness of a plurality of points of the metallic matrix is measured by a shape test device, and a flatness margin of error H between a reference level and the flatness of the metallic matrix is calibrated using the least square method. A controller determines whether the points of the metallic matrix need to be shaped by comparing the flatness margin of error H and a permissive error range K. The controller calibrates a descending distance P by a mathematical formula of P=M+[(H−K)/D]/N+L. A shaping device shapes the metallic matrix according to the descending distance P and a shaping time. The above steps are repeated until the flatness of the metal is within the permissive error range K. | 05-07-2015 |
| 20150128674 | SHOT PEENING METHOD, SHOT PEENING EVALUATION METHOD, AND SHOT PEENING EVALUATION ASSEMBLY STRUCTURE - In a trial peening step, a shot peening process is applied to a back face | 05-14-2015 |
| 20160089712 | VERSATILE DYNAMIC STAMPING/RESTRIKING TOOL - A stamping tool and a method for deforming a part with the stamping tool are disclosed. The stamping tool may include an array of striking members (e.g., pins), each striking member capable of being actuated independently with respect to the other striking members. In some embodiments, the stamping tool is part of a system having a vision system and a computing device. The vision system is capable of scanning the part to determine a location or location in which the array of striking members will engage the part. The deforming operation can include a rework operation subsequent to another process, or alternatively, the deforming operation can include deforming the part such that the part includes a three-dimensional shape. Also, the part can be a two-dimensional or three-dimensional part made from metal (e.g., aluminum, steel) or plastic. | 03-31-2016 |
